It is no secret the M157 is going to be a popular platform to tune, especially the non performance package cars. This CLS63 did not include the performance package and therefore has much more room to play with. Gains are about 75-80 horsepower at the wheels and 80-90 torque at the wheels on what we believe is 93 pump gas. We realize the graph is incredibly small and difficult to read and have requested a larger graph from OE Tuning. This post will be updated once we receive it.
